new and useful- Improvement in Car-- Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it app'ertainsto make and use the same, reference being bad to the accompanying drawings, in

Figure l is a side elevation ofa portion of a cartruck embodying thefeatures of my invention; Fig. 2 is a plan view, partly in section, of the parts shown in Fig. 1; Fig. 3 is 'a-fsection taken approximately on the line 3"3 -ot' Figfi, the upper portion of the 'rame being-broken away to more clearly show the. movable bolster support;

'Fig. 4 is a perspective view ofthe 'mdvable bolster support; Fig. 5 is aside elevation of a portion of a car truck provided with a slightly modified form of the movable bolster support shown in Fig. 4; Fig. Gisa plan view, partly in section, of the bolster,. bolster support, and truck frame shown 111- Fig. 5; Fig. 7 1s a side elevation, partly in section, illustrating another modification;

' Fig. 8 is a view similar. to Fig. 3, showing the rockable bolster support seen inQ Fig. 7;

and Fig. 9 is a perspective view of the bolster support shown in Fig. 7, and Fig. 8.

. This invention relates to improvements-in car trucks of the-lateral motion type, one of the objects being to produce a novel and efficient device which will allow the truck bolster to .move relative to the truck frame and cause the bolster to returxrto normal position al'tersuch movement. I

Another object is to provide a car truck ha ring a bolster of the standard type and a truck frame of the standard type combined with a lateral motion device which allows the bolster to be very easily fitted to, or removed from, the truckframe.

In the accompanying drawings :A designates a portion. of a-well known form of' truck frame (Figs. 1 and 2) which is shown merely to illustrate the function of the lat 'eral motion devices, it being understood that thi mvention is not in any way limited to a truck frame constructed as herein shown.

There I refer to a truck frame in the claims -I mean-to" include a pair of side frames 'connected together, or any other suitable ordesirable truck frame structure.

Specification. of Letters Patent.

It will now be readily understood that the rockers 7 upon which the bolster is mounted, allow the bolster-to 11love laterally relative to the truck frame and that the springs 3 are prevented from moving laterally by the plate 4 arran the springs. the bolster rests on. the flattened or slightly curved top face of the rockcrsF, said rockers are'normally held in the position seen in Fig. '3, wherein the upper ends of the inclined abutments 9 lie adjacent to the bolster lugs 10 and the lower ends of said abutments are adjacent to the walls 2 of the bolster receiving Opel-ling. During the lateral movement of the bolster, abutments 9 are tilted toward the walls 2 of ,the bolster receiving opening and when the 'ed between said rockers .and-

bolster G shown in Fig. 5 and Fig. 6, rests on a movable member B and is provided with two pairs of abutments or lugs 10. The lugs 10 at one side of the bolster are alined with the truck frame A and the lugs 10 on the opposite side thereof are alined with abutments on the movable member B. The member B is arranged between the bolster and the truck frame and has abut- .ments 9 adapted to engage said frame.

faces 'on the spring plate 3.

Only one of the movable members B is employed at each end of the bolster and the rocker 7 forming part of said 'movable member is therefore preferably longer than the rocker 7 as shown in Fig. 4.

Figs. 7 to 9 inclusive illustrate a-modificd form comprising a bolster B having lugs 10 adapted to engage the frame A. The side faces of the bolster are provided with recesses having curved top walls 11 which rest on the curved top faces of rockable bolster supports 12. Each rockable member 12 is provided with a pair of curved extensions 13 seated on correspondingly shaped Obviously these rockable bolstersupports 12 allow the bolster to move laterally until the bolster lugs 10 engage the truck frame, and after 'such movement the bolster is restored to normal position by the supports 12 which tend 'to return to the position shown in Fig. 8.

by Letters Patent is 1. A car truck having a bolstcr provided with a flat bottom face, and a rocker upon which said flat face is seated, said rocker be ing interlocked with the bolster.

2. A lateral motion car truck comprising a frame having a bolster receiving opening, rockable bolster supports, and a bolster resting on said rockable bolster supports, a portion of each of said rockable supports being interposed between the bolster and a side wall of said opening.

3. A lateral motion car truck comprising a frame, rockable bolster supports, and a bolster seated on said rockable Supports, a

poi-lion of each of said supports being intersprings, a rockable bolster support resting on said plate, and a bolster restin on said rockable support, said rockable bo ster support being located partly below the bolster and'partly between said frame and the side of the bolster.

a side face 'of 5. A lateral motion car truck comprising" a frame, springs supported by said frame, a"

vertically movable plate supported by said springs, a rockable bolster support resting on said plate, and a bolster resting on said rockable support, saidrockable bolster support being provided with abutments adapted to engage said frame.

6. A lateral motion car truck comprising a frame, a bolster, springs, and rockable bolster supports arranged between said bolster and springs, said bolster supports being provided with abutments adapted to engage said frame.

7. A car truck comprising a frame, a bolster, and rockable bolster supports provided with abutments having inclined faces adapted to engage said frame.

8. A car truck comprising a frame, a bolster, and rockable bolster supports provided with abutments having inclined faces adapted to engage said bolster.

9. A lateral motion car truck comprising a frame, a bolster, springs, and a rockable bolster support a portion of which is arranged between said bolster and springs, said rockable bolster support being provided with abutments adapted to be engaged by the bolster.

10 A lateral motion car truck comprising a frame, a bolster, springs, and a rockable bolster support a portion of which is arranged between said bolster nd springs, said rockable bolster support being provided with abutments adapted to engage said frame and bolster.

11. A car-bolster support comprising ,a rocker, substantially D-shape in cross section, said rocker having a curved bottom face and a comparatively flat top face adapted to constitute aseat for the bolster, and a pair of abutments extending from said rocker.
